Thanks. For what it's worth I had tried signing up a few weeks ago and used the contact us to mention the captcha issue with no response. Then tried logging in with FB and that worked so I just left it as is, but today I timed out during a long post and that logon screen didn't have a FB logon option so I thought I'd try again.

Happy to delete the FB one or if you can merge this account to a new registered account that'd be good, but not real necessary as I only have 1 post once so far.

"As for the captcha, it's not quite yet fully broken, but Google is expiring the product very soon which is why users may see it from time to time. They can just re-generate the captcha and the expiration notice will go away. "
